    from django.http import httpresponse
ImportError: cannot import name 'httpresponse' from 'django.http' (C:\Users\aviba\Envs\test\lib\site-packages\django\http\__init__.py)

应用程序的urls.py

from django.urls import path
from . import views

urlpattarns = [
    path('',views.home, name='home'),
]

该应用的views.py

from django.shortcuts import render
from django.http import httpresponse

def home(request):
    return httpresponse("Hello Django")

项目的urls.py

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('',include('firstapp.urls')),
    path('admin/', admin.site.urls),
]

Answer 1

python中的

模块区分大小写，是console.log(obj); // {country: false, state: true, fruits: true}而不是HttpResponse

Answer 2

尝试使用 views.py ：

from django.shortcuts import render
from django.http import HttpResponse

def home(request):
    return HttpResponse("Hello Django")

这里的httpresponse区分大小写，因此我们以这种方式使用它。阅读此内容可能会对您more有帮助。

Answer 3

确保您使用Python3作为解释器。我遇到了同样的问题（使用Django 3.1.2），并且在选择了正确的解释器（python 3.7.8）之后，此问题已得到解决。

我该如何解决无法导入“ django.urls”的错误？
